Diamond Core Drilling Rig XY-44A Spindle Type Diesel Engine 1400m Depth
XY-44 core drilling rig is mainly adapted to diamond bit drilling and carbide bit drilling of solid bed. It can also be used for engineering geology and groundwater exploration; shallow layer oil and natural gas exploitation, even hole for sap ventilation and sap drain. The drilling rig has compact, simple and suitable construction. It is light, and can be assembled and disassembled conveniently. With a large number of rotation speed series and appropriate range of rotation speed, low speed with high torque. The drill is suitable for alloy core drilling and diamond core drilling, as well as engineering geological exploration, water well and foundation hole drilling.

Features of XY-44 core drilling rig:
(1) XY-44 core drilling rig is with big spindle inner
diameter(Ф93mm), double hydraulic cylinder for feeding, long stroke
(up to 600 mm), and strong process adaptability, which is very
suitable for wire-line coring drilling of large diameter drill
pipe, and is helpful to improve drilling efficiency and reduce hole
accident.
(2) XY-44 core drilling rig has large drilling capacity, and the
max rate drilling depth of Ф71mm wire-line drill rod can reach 1000
meters.
(3) XY-44 core drilling rig is light in weight , and can be
assembled and disassembled conveniently. The drill has a net weight
of 2300 kilogram, and the main machine can be disassembled into 10
components, which make it to be flexible in movement and suitable
for mountain work.
(4) The hydraulic chuck adopts one-way oil supply, Spring clamp,
hydraulic release, chuck clamping force, clamping stability
(5) Equipped with water brake, the rig can be used for deep hole
drilling, smooth and safe under drilling.
(6) XY-44 core drilling rig adopts single gear oil pump to supply
oil. Its virtues are installation simple, eay to use, low
consumption of power, low oil temperature of hydraulic system and
stable working. The system is equipped with hand oil pump, so we
can still use the hand oil pump to take out the drilling tools even
the engine can not work.
(7) XY-44 core drilling rig is compact in structure, rational in
overall arrangement, easy maintenance and repair.
(8) XY-44 core drilling rig has a low center of gravity, long skid
stroke, and is fixed firmly, which bring good stability with high
speed drilling.
(9)Equipped with shockproof instrument, and the instrument has long
life, which can help us grasp the hole situation. Less control
lever make the operation flexible and reliable.
